#### Search 

```
`sysmon` EventCode=6 Signature="Noriyuki MIYAZAKI" OR ImageLoaded= "*\\WinRing0x64.sys" 
|  stats  min(_time) as firstTime max(_time) as lastTime count by  Computer ImageLoaded Hashes IMPHASH Signature Signed 
| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)` 
| `xmrig_driver_loaded_filter`
```

#### Macros
The SPL above uses the following Macros:
* [security_content_ctime](https://github.com/splunk/security_content/blob/develop/macros/security_content_ctime.yml)
* [sysmon](https://github.com/splunk/security_content/blob/develop/macros/sysmon.yml)

> :information_source:
> **xmrig_driver_loaded_filter** is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

#### Required field
* _time
* Computer
* ImageLoaded
* Hashes
* IMPHASH
* Signature
* Signed


#### How To Implement
To successfully implement this search, you need to be ingesting logs with the driver loaded and Signature from your endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the Sysmon TA.

#### Known False Positives
False positives should be limited.

#### RBA

| Risk Score  | Impact      | Confidence   | Message      |
| ----------- | ----------- |--------------|--------------|
| 80.0 | 80 | 100 | A driver $ImageLoaded$ related to xmrig crytominer loaded in host $Computer$ |


> :information_source:
> The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
